How to add quotes " " to every element in non numeric column of a dataframe saved as CSV

Question

I have DataFrame

id,type,value
1,8,value1
2,2,value2
3,7,value3
4,3,value4
5,10,value5
6,3,value16

I want to add to the value id and value of the CSV file to be allocated quotes

"1",8,"value1"
"2",2,"value2"

What better way to do it

Answer 1

converting to strings and using +

df.update('"' + df[['id', 'value']].astype(str) + '"')
print(df)

using applymap

df.update(df[['id', 'value']].applymap('"{}"'.format))
print(df)

---

Both yield

    id  type      value
0  "1"     8   "value1"
1  "2"     2   "value2"
2  "3"     7   "value3"
3  "4"     3   "value4"
4  "5"    10   "value5"
5  "6"     3  "value16"
